My school is trying something new this year with RTI and I am loving it! This year we have broken down our students into math and reading groups based on strengths and weaknesses. Each day we have a 30 minute RTI block with the whole 4th grade.
I am working with the high reading group and have been using Alyssha Swanson's Close Reading passages.
The bundle includes literature and informational text. Right now we have been using the high interest informational texts. The students have really enjoyed the topics of the articles and we have also had fun using the Chromebooks to investigate the topics even further.
If you are looking for something to challenge your higher readers, I highly recommend this product. Not only are the passages challenging and engaging, but they include higher level questions that go along with each passage.
